The short answer: BookFi is gone, and it isn’t coming back. The free ebook site — known at various times as BookFi, BookSee and BookOS — shut down years ago after repeated copyright enforcement, and anything using the BookFi name today is an unrelated clone. The good news is that what replaced it is better than most people realise: there are large, completely legal libraries where you can read millions of books for free. The catch is that a few of the “alternatives” on old lists are pirate sites themselves — one of them was seized by US authorities — so it pays to know which is which.
What happened to BookFi?
BookFi built its name the same way every shadow library does: a huge catalogue of books and academic papers, free to download, no questions asked. The problem is that most of those books were uploaded without the permission of the authors and publishers who own them.
That model never survives contact with copyright law for long. BookFi’s domains were blocked, seized or abandoned in wave after wave of enforcement through the 2010s, and the site eventually disappeared for good. As of October 2026 there is no official BookFi. If you find a site using the name, treat it the way you’d treat any too-good-to-be-true download page: the books are pirated, the ads are aggressive, and some clones exist purely to push malware or harvest sign-ups.
BookFi’s story is the standard life cycle of a pirate library — grow fast, get noticed, get shut down. We told the same story in our explainer on what happened to OceanofPDF, and it ends the same way every time.
The best legal BookFi alternatives
Every site below is free to use and legal. Together they cover classics, textbooks, new releases and indie fiction — most of what people went to BookFi for, minus the legal and security risks.
1. Project Gutenberg
The original free ebook library, run by volunteers since long before “ebook” was a word. Project Gutenberg offers tens of thousands of books whose US copyright has expired — Dickens, Austen, Twain, Conan Doyle, and thousands of less famous authors — in EPUB, Kindle and plain-text formats, with no account and no fees.
Legal status: Fully legal. Public-domain works only.
Best for: Classics, literature, history, philosophy.
Safety: Completely safe — no ads, no download tricks.
2. Standard Ebooks
Standard Ebooks takes public-domain books (many sourced from Project Gutenberg) and produces carefully proofread, beautifully formatted editions with proper typography and modern covers. The catalogue is smaller than Gutenberg’s, but the reading experience is noticeably better — these are the editions to choose when a title is available on both.
Legal status: Fully legal. Public-domain works, released under open terms.
Best for: Readers who care about formatting quality.
Safety: Completely safe.
3. Open Library
Open Library, a project of the Internet Archive, aims to catalogue every book ever published and lets registered users borrow scanned copies of in-copyright books for a limited period, like a digital public library. One honest caveat: its lending programme was scaled back after a US court ruled against the Internet Archive in a publisher lawsuit in 2023, so fewer recent titles are borrowable than a few years ago. Plenty still is, and its public-domain collection remains freely downloadable.
Legal status: Legal, with the lending restrictions described above.
Best for: Out-of-print and hard-to-find titles.
Safety: Safe — it’s run by the Internet Archive, a long-established non-profit.
4. Internet Archive
Beyond Open Library, the Internet Archive’s main collection holds millions of texts: public-domain books, old magazines, manuals, government documents and historical material you won’t find anywhere else. Much of it is downloadable in full; some items are borrow-only.
Legal status: Legal for its public-domain and openly licensed holdings; lending titles follow the same restrictions as Open Library.
Best for: Research, archives, obscure and historical material.
Safety: Safe.
5. Libby
Libby is the app for your local public library, and it’s the closest legal equivalent to what BookFi promised: current bestsellers, new releases and popular non-fiction, free. You sign in with a library card (most libraries let residents apply online), borrow ebooks and audiobooks, and they return themselves when the loan ends. There can be waiting lists for popular titles, exactly like a physical library.
Legal status: Fully legal — it’s your library.
Best for: New and popular books, audiobooks.
Safety: Completely safe.
6. Google Books
Google’s book search lets you read full texts of public-domain books and generous previews of in-copyright ones, and it links out to stores and libraries for the rest. It’s less a library than a discovery tool — but for checking whether a book is worth tracking down, or reading the classics it hosts in full, it’s excellent.
Legal status: Fully legal.
Best for: Previews, research, public-domain full texts.
Safety: Completely safe.
7. Smashwords (free section)
Smashwords is a long-running self-publishing platform where independent authors set their own prices — and thousands set theirs to free, either permanently or as promotions. Quality varies, as it does with all indie publishing, but it’s a genuine source of free contemporary fiction and non-fiction that the author actually chose to give away.
Legal status: Fully legal — prices are set by the rights holders.
Best for: Indie fiction, new authors, niche non-fiction.
Safety: Safe.
What about the other “alternatives” on old lists?
Older BookFi alternative lists — including the previous version of this article — recommended sites that are not legal alternatives at all. Here’s the honest status of the famous names:
- Library Genesis (LibGen) is a shadow library that distributes books and papers without permission. It is not legal, whatever its fans argue about academic access. We’ve covered it in detail in our guide on how LibGen works and whether it’s legit and safe.
- Z-Library was BookFi’s biggest successor — and in November 2022 its main domains were seized by US authorities and its alleged operators were arrested and charged. It later resurfaced in a reduced, harder-to-reach form, but it remains a pirate site carrying pirated books, and the sites claiming to be its “official mirrors” are a magnet for scams.
- B-OK / Bookzz, once recommended everywhere, was part of the same network as Z-Library. Its domains were among those seized, and it is effectively gone.
- PDF Drive mixes public-domain material with in-copyright books uploaded without clear licensing. Treat it as a grey area at best.
The pattern to remember: when a free site offers new, commercial books at no cost with no library card and no publisher’s name anywhere, the books are pirated and the site is living on borrowed time.
Frequently asked questions
Is BookFi ever coming back?
Almost certainly not. Its domains were lost to enforcement years ago, and no original operator has resurfaced. Any site currently using the BookFi name is an unaffiliated clone — avoid it.
Are the legal alternatives really free?
Yes. Project Gutenberg, Standard Ebooks and the Internet Archive are free with no account at all. Open Library and Libby need a free account (Libby needs a library card). Google Books previews are free; Smashwords’ free section is free because authors chose that price.
Can I get new bestsellers legally for free?
Through Libby, yes — that’s exactly what public libraries are for. You may have to join a hold queue for the most popular titles, but the book is the real, complete, legal edition.
Is it illegal to download from sites like Z-Library or LibGen?
Downloading copyrighted books without permission is copyright infringement in most countries, and uploading or sharing them is treated more seriously still. Enforcement usually targets operators rather than individual readers, but “usually” is not “never” — and the malware and scam risk on clone sites is a practical danger regardless of the legal one.
What if the book I need isn’t on any legal site?
Check Libby and Open Library first, then Google Books for a preview, then your library’s physical catalogue or interlibrary loan. For textbooks, older editions are usually far cheaper second-hand and cover nearly identical material.
The bottom line
BookFi is gone, and so are several of its most famous replacements — seized, shut down, or reduced to scam-prone clones. Meanwhile the legal options have quietly become excellent: Project Gutenberg and Standard Ebooks for classics, the Internet Archive and Open Library for research and rarities, Google Books for discovery, Smashwords for indie reads, and Libby for the new releases people actually want. Everything BookFi promised, minus the takedown notices and the malware.
